"""
Middleware component that wraps the login_required decorator around
matching URL patterns. To use, add the class to MIDDLEWARE_CLASSES and
define LOGIN_REQUIRED_URLS and LOGIN_REQUIRED_URLS_EXCEPTIONS in your
settings.py. For example:
------
LOGIN_REQUIRED_URLS = (
r'/topsecret/(.*)$',
)
LOGIN_REQUIRED_URLS_EXCEPTIONS = (
r'/topsecret/login(.*)$',
r'/topsecret/logout(.*)$',
)
------
LOGIN_REQUIRED_URLS is where you define URL patterns; each pattern must
be a valid regex.
LOGIN_REQUIRED_URLS_EXCEPTIONS is, conversely, where you explicitly
define any exceptions (like login and logout URLs).
